T0 all/whom it may concern Be it known that I, OTTO BAKER, a citizen of the United States, residing at Sparkill, in the county of Rockland and State of New'York, have inventedl certain new and useful Improvements in Traps for Returning Vlater of Condensation; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to water distribution, and more especially for feeders of that type which pass the water of condensation back to the boiler or hot well; and the object of the same is to produce a trap for this purpose having automatically operated valves for controlling the iiow of water and accomplishing the end desired.

Details of the invention are set forth in the following specification and illustrated in the drawing which shows a diagrammatic elevation of the controller, receiver, the cylinders wherein condensation occurs, and the A pipes; and the drawing also shows the valve mechanism 1n elevation, and thel actuating mechanism therefor.

I will say at the beginning that my improved trap is shown in the accompanying drawings as applied to dryers or cylinders C, herein illustrated as disposed in several groups or banks, although I reserve the, right to apply it to any device or devices herein typiied by the'cylinders C and ill which'drying is done by It is ywell'known ythat such an yexcellent heated steam. steam when hot and dry is medium for drying purposes, but it cools rapidly and eventually condenses, and 0f course the water of condensation will not dry anything. My improved trap` is intended for. removing this water of condensation from the various cylinders and driving it back to the hotwell or water heater of the boiler not shown) by means of steam pressure of erably from the same boiler which supplies the superheated steamto the cylinders.

It will be obvious that details of construction, other than hereinafter set forth, are not necessary to carry out the system; and therefore the general diagrammatic view illustrated in the drawings will` ,now be described.

The drying cylinders C are here shown means of super- -lowermost stop i nally a out fifty pounds, taken preff 4cumulates within the ,receiver and controllerf is ejected from the same byineans of steampressure from the boiler (not as arrangedv in groups or banks, and one end 1 (here the nearmost end) of each is con nected Iby an outlet pipe 2 with a drain pipe The drain pipes 3 from the several groups of `cylinders C lead along proper courses, each through a control valve 4:,*and finally they deliver the water of condensation into a receiver or tank 5 which is-preferably of considerable size and cylindrical and upright as shown. From the bottom of this tank leads an outlet pipe 6, through a suitable check valve7 and across the head of a T-coupling 8, thence through another check valve 9 having an adjustable Weight 9', and along a pipe 10 tothe hot well of the boiler (not shown), and the stein of said T-coupling 8 is connected with theI lower end of an upright cylindrical con troller 11 standing alongside they receiver 5 but internally disconnected therefrom eX- cepting through the pipe 6 and the check valve 7 as described.

The controller 11 contains a guide 12 in which moves an upright rod 13 standing along the aXis of the controller body and vextending through an opening in its domeshaped head; and on this rod between stops 15 and 16 attached thereto moves a nipple 17 depending from the center of a float 18 which is ofinverted Icup-shape and has a surrounding flange 19 ittingloosely within the body 11.l It follows that when water T-coupling 8 beneath said float, air is trapped within the latter between the nipple and flange, and the result is that as the water level rises the float lrises andits nipple slides upward along'the rod 13 until it contacts with the uppermost/'stop 15 when the rod will be raised bythe float;

rises through the lon the other hand, as the water levelfalls,

the `float falls 'until its nipple strikes the 16 when the rod will be moved downward with the float. yEnter` of the casing 11 and above its domeshaped head, this rodcarries two other stops 20 y The water of [condensation which Y acinlet valve 23.' The character of this valve and for they purpose of forcing is unimportant, but it is shown as capable of being opened by raising a lever 24, and it is important that when the steam is being admitted to the controller thesteam out-let pipe 25 therefrom should be closed by its valve 26 which is shown alsoy as actuated by a lever 27. The pressure of the steam within the controller drives out the water therein7 which passes down through the T-coupling 8, closes the check valve 7 to the left, and is sufficient to open the check valve 9 to the right, so thatthe water flows to the hot well. .On a reversal of the position of the two of live `steam to the controller is cut off and this steam is permitted to pass out the pipe 25 which leads to a T-coupling l29, downward from which extends a pipe 28 whereby the water of condensation which may arise throughout this course can be 'carried through a check valve 3() and into the water outlet pipe 6 whence it finds jits way to the hot well through the course above described. But the outflowing steam-now relieved of its pressure and of much of its heat and therefore which we may well call vapor-is carried upward from the ,T- coupling by a pipe 3l and into the firstof the series of cylinders7 here marked C", which I propose to give over entirely to the work of condensing vapor as it will condense about three times as much as any other cylinder. rIhe outlet for densation from this cylinder is through a pipe 32 to a drain pipe 33 which leads back to the hot well in a manner not necessary to illustrate.

The specific mechanism which I employ for simultaneously openingthe steam inlet valve 23 and closing the steam outlet valve 26, or the reverse, forms an important feature of this invention, and I call it the valve actuator. The numeral 40 designates a substantially horizontal headed cylinder jin which is a globular weight 41 adaptedto move therein between its heads 42 and 42, and 43 is a disk-like hub on which this cylinder is supported hub having two arcuate slots 45` struck around its center as shown.V In each slot is adjustably secured a stub stop, formed preferably in the shape of shaft 46, and one stop underlies the lever 24 the other rollerunderlies the lever 27 of the valve 26. From one end of saidcylinder projects a fork 49 which straddles the rod 13between its stops 20 and 2l. When now the iioa-t rises within the controller, the stop 21 eventually lifts the fork and tiltsl the actuator around its pivot so that the ball rolls to the left end of the cylinder 40, and the lever 24 of the steam inlet valve 23 is raised to open said valve and admit the steam at fifty poundspressure. Meanwhile the left hand roller permits the, descentgof valves 23 and 26, theinlet densation at the bottom the water of conover a pivot 44, the,

of the valve V23 while the lever 27 of the steam outletv valve 26, which lever is weighted as shown at 27; and the action above described takes place. After suiiicient .water has been expelled from the receiver and controller to permit the float to fall, the descent of the rod 13 causes the uppermost stop 20 to draw downward on the fork at one end of the cylinder 40, the latter rocks the disk around its pivot, and a reverse action takes place so that the steam inlet valve 23 is closed by the weight 24 on its lever 24, and the steam outlet is opened.

Vhen the steam has been practically all exhausted from the controller l1, said mechanism acts to again open the steam inlet valve 23 and close the steam cutletvalve 26, and the action is repeated; but as soon as the steam pressure closes the check valve 7 there is no outlet for the water of conof the receiver 5, and therefore the water iiowing into the receiver from the various drain pipes accumulates within it. The result is that the air above this water, which we may also call vapor, must be handled, and for this purpose I provide an outlet pipe 50 leading upward to a header 51 which may be connected through a pipe 52 and hand valve 53 with the first cylinder above mentioned although said cylinder C will probably be working to its full capacity to handle the water of condensation from the exhausting steam. I would therefore connect the header by another pipe 54 and a hand valve 55 with the second cylinder C2 of the series, and give over this cylinder as well as the first cylinder C" for handling the condensed vapor; and the water of condensation from this cylinder may lead through an outlet yp ipe 56 into the drain pipe 33 and thence into the hot well as above described. If the live steam fed through the pipe 22 into the controller is under a greater pressure or temperature than normal, or if for any reason its condensation occurs more rapidly than the first cylinder C can handle, by opening the valves 53 and 55 the second cylinder C2 can be thrown into connection with the first one through the header 51, and act with it to condense the steam as well as to condense the vapor arising through the pipe 50. In other words, if the plant be large, I give over the first two cylinders which w'll be the coolest of the series for v.condensingwhat Vmight be called vapor. In

like manner I may give over the cylinders, of the next group, herein numbered C3 for the use of handling the exhaust steam from the engine (under about fifteen pounds pressure) but this need not be described in detail.

Thus itwill be seen that I have produced a machine having details of construction `whereby the live steamled into the pipe 22 alternately ejects the water of condensation from the controller and forces it back to the hot well-then cuts itself oi at the inlet and opens up the outlet so that its lower end draws in another charge of the water of condensation from the receiver in which it has been meanwhile accumulating. The action is entirely automatic, and the various hand valves inthe inlets to and outlets from the several cylinders will doubtless be under control of workmen who are quite remote from this machine which I would by preierence locate in the basement of the building and near the boiler.

What is claimed as new is:

l. An upright cylinder having inlet and outlet openings, valves controlling them, pivoted levers connected with the valve stems and projecting` toward each other, and weights for moving said levers to normally close sail valves; combined with a centrally pivoted disk disposed between said levers and having arcuate slots in its opposite sides struck around its pivot, stops adjustably mounted in said slots below the levers, a normally horizontal track carried by and across the upper edge of said disk, a moving Weight on said track, and means for turning the disk on its pivot and swinging the track over said pivot by the rise and tall of water within said cylinder.
